circumference =16π = 2πr
16π = 2πr
8 = r units
Area = πr²
= 64 π
= 200.96 unit²
----
The formula for the circumference of a circle is 2Ïr. Therefore...
2Ïr = 16Ï Reducing gives you...
Ïr = 8Ï
r = 8
Now, you have found the radius of the circle. Using the formula for the area (Ïr²) you can plug in the value for the radius.
area = Ï(8)²
area = 64Ï units²
